But that is not all - you need an appropriate prop.A large dia with small pitch (eg, 10x4) will give lot of thrust but low forward speed.At 9000rpm, or 150 revs/sec, a 4" pitch prop cannot exceed 50ft/sec, or 55kmph.

Whether this is safely above the stalling speed or not depends on the type of model and its wing loading.A glider type will fly with low power, low rpm, low pitch.A jet type will need high power and high rpm and/or high pitch.

For a more specific answer you need to post a picture of the model and give details of the motor, prop, ESC, battery, wing area and all up weight.Best of luck.

Sir, I have used an avionic 2836(1120KV) motor ordered from Rcbazzar.I calculated its thrust on a somewhat test bench.Prop is 9x4.7Ebattery is Zippy 1300Mah 20c 3 cell lipo.Esc is turnigy multistar 45 amp.

Since my budget is low i m going for mild aerobatic. its my first flight just want it to see flying....

Sir, I did view the specs and that's why i did buy that motor.But i wanted to test it myself so that i could confirm it.Yes i have built the model from a proven design.Thank you for correcting me now i ill focus on stability.
